| Device Names | Xiaomi 14T Pro (global/EEA/India/etc.) and Redmi K70 Ultra / K70 Extreme Edition (China) – shared rothko platform. |
|---|---|
| Codename | rothko – confirmed by HyperOS code and firmware tools as the common codename for both devices. |
| Chipset | MediaTek Dimensity 9300+ (4 nm) flagship SoC with Immortalis‑G720‑class GPU, tuned differently between Redmi K70 Ultra and Xiaomi 14T Pro. |
| Display | 6.67‑inch OLED, 1220 × 2712, up to 144 Hz refresh rate, HDR10+/Dolby Vision and peak brightness around 4000 nits. |

| Main Issues Reported | HyperOS 2 users frequently report battery drain, overheating and worse endurance after some updates until they factory‑reset or clean‑flash a stable ROM. |
| Benefits of These ROMs | Provide clean, region‑correct images for unbricking, undoing bad OTAs/mods and moving to builds with the latest security patches and stability tweaks. |

| Required Tools | Xiaomi Mi Flash Tool on Windows or fastboot scripts like flash_all.bat from inside each ROM package. |
| Bootloader Status | Bootloader unlock is mandatory for Fastboot flashing; OTA recovery updates usually require a locked, unmodified device. |
| Use Cases | Upgrade to Android 16, recover from bootloops, fix failed OTAs, revert from custom ROMs and clear persistent HyperOS bugs on Xiaomi 14T Pro / Redmi K70 Ultra. |
Flashing Requirements
- 💾 Backup data: Fastboot flashes will usually wipe apps, accounts and internal storage; save photos and files before starting.
- 🔋 Charge above 50 %: Low battery during flashing risks shutdowns and permanent bricking.
- 💻 Windows PC & USB‑C cable: You need a Windows computer, Xiaomi USB/ADB drivers and a stable cable for Mi Flash or fastboot.
- 🔓 Unlocked bootloader: Use Xiaomi’s official unlock procedure on your rothko device before flashing any rothko_*_images_*.tgz ROM.
How to Flash the Firmware
Method 1: Xiaomi Mi Flash Tool (Fastboot ROM)
- Install tools & extract ROM: Install Xiaomi USB drivers and Mi Flash Tool on your PC, then extract the chosen Fastboot ROM (for example, rothko_global_images_OS2.0.225.0.WNNMIXM_… or rothko_images_OS3.0.3.0.WNNCNXM_…) into a simple folder.
- Enter fastboot mode: With the bootloader unlocked, power off the phone, hold Volume Down + Power to enter fastboot, and connect it via USB‑C.
- Load firmware in Mi Flash: Open Mi Flash Tool, click Select and point it to the extracted rothko ROM directory containing images and scripts.
- Choose “clean all” and flash: In Mi Flash options, select “clean all” (avoid relock), then click Flash and wait while all partitions are written.
- Reboot and let HyperOS settle: Once Mi Flash reports success, let the device reboot; the first Android 15/16 boot can take several minutes as apps and data are optimized.
For a step‑by‑step Mi Flash tutorial with screenshots and troubleshooting, see: Full Tutorial: Flash Xiaomi Firmware with Mi Flash Tool.
Method 2: Fastboot Script (flash_all.bat)
- Set up platform‑tools: Download Google’s Android platform‑tools and confirm the fastboot command works in your terminal or Command Prompt.
- Fully extract the ROM: Unpack the .tgz Fastboot file until you see partition images and scripts such as flash_all.bat.
- Connect in fastboot: Boot your rothko device into fastboot, connect it via USB‑C and verify detection with fastboot devices.
- Run the script: Execute the “flash all” script that keeps the bootloader unlocked and wait as all partitions are flashed automatically.
- Finish setup and monitor: After reboot, complete setup and monitor battery life and thermals over several days while HyperOS completes background optimization.

Frequently Asked Questions (FAQs)
What issues can these rothko ROMs fix?
Correct regional Fastboot ROMs can recover Xiaomi 14T Pro / Redmi K70 Ultra from bootloops, severe lag, broken system apps and many HyperOS 2/3 software issues like abnormal drain or overheating after bad OTAs.
How do I confirm my phone is a rothko device?
Check Settings → About phone → Version and verify that firmware trackers list your model and region under codename rothko (Redmi K70 Ultra or Xiaomi 14T Pro) before flashing.
Which file should I choose for my region?
China users should use WNNCNXM, Global WNNMIXM, EEA WNNEUXM, while Russia, Indonesia, Taiwan, Turkey and Japan should pick VNNRUXM, VNNIDXM, VNNTWXM, VNNTRXM and VNNJPXM respectively; VNNMIDC is a special global “dc” channel.
Do Android 16 WNN* builds fix HyperOS 2 battery drain?
Android 16 WNNMIXM/WNNEUXM and HyperOS 3 WNNCNXM add new security patches and system optimizations, and many users see better stability after a clean flash, but final endurance still depends on usage and apps.
Can I cross‑flash China WNNCNXM on a Global WNNMIXM phone?
Cross‑flashing is technically possible on an unlocked device but can break OTAs, carrier features and may brick the phone if you relock, so staying on your native region is much safer.
Why does my phone still run warm after updating?
HyperOS performs heavy background tasks after major updates, and high‑end SoCs like Dimensity 9300+ generate heat under sustained load, so community guides suggest letting a few charge cycles pass and tuning background apps before assuming hardware faults.
